Explanation: Not the Hubble Space Telescope’s latest view of a distant galactic nebula, this illuminated cloud of gas and dust dazzled early morning spacecoast skygazers on August 29. The snapshot was taken at 3:17am from Space View Park in Titusville, Florida. That’s about 3 minutes after the launch of a SpaceX Falcon 9 rocket on the CRS-23 mission to resupply the International Space Station. It captures drifting plumes and exhaust from the separated first and second stage of the rocket rising through still dark skies. The lower bright dot is the second stage continuing on to low Earth orbit. The upper one is the rocket’s first stage performing a boostback burn. Of course the first stage booster returned to make the first landing on the latest autonomous drone ship to arrive in the Atlantic, A Short Fall of Gravitas.

说明: 在8月29日清晨，让美国太空海岸观星人看得目眩神迷的这团明亮的气体与尘埃云，并不是哈勃太空望远镜最新的遥远星云拍摄标的。这张摄于佛罗里达州泰特斯维尔市．太空观景公园的照片，取像的时间是早上3点17分。大约是太空探险公司猎鹰九号火箭执行CRS-23任务补给国际太空站，发射升空的3分钟之后。影像记录了火箭向宁静黝黑的天空攀升、漂飞的烟尘、以及第一级和第二级火箭分离时排出的气体。影像右下的亮斑，是往低地球轨道前进的第二级火箭，中上方的亮斑，则是在进行返程喷燃的第一级火箭。第一级推进器将返回，并首次降落在停泊于大西洋的最新无人驾驶回收船“缺乏庄严肃穆号”之上。
